The centaurs of Greek mythology are creatures that are part human and part horse. They are usually portrayed with the torso and head of a human, and the body of a horse. Centaurs are the followers of the wine god Dionysus and are well known for drunkenness and carrying off helpless young maidens.
If both healthy parents carry the same altered recessive. gene, then each child they have has a 25% (1 in 4) risk of. inheriting the altered gene from both parents and therefore. being affected. For each child, regardless of their sex, the. risk is the same = 25%. Children of couples who are both carriers of the same. altered recessive gene have a 50% (1 in 2) chance of. inheriting one copy of the altered gene from one of their. parents. If this happens, they are healthy carriers. themselves.
If the disorder is dominant, anybody with one copy of the disorder is not reproductively successful, and that single genetic copy does not get copied to the next generation.However, recessive genetic disorders require that the organism gets two copies of the gene for it to be a problem with survival and reproduction.hey are mostly recessive because the alleles have to have two recessive traits in order to classify the gene as a recessive gene. Also if you have one recessive trait and another dominant the dominant (emphasis on the word) allele will make the gene have a dominant trait.
